我想要得到一个确认消息点击删除(这可能是一个按钮或图像)。如果用户选择“Ok”,那么删除就完成了,否则如果点击“Cancel”,什么都不会发生。

当点击按钮时,我尝试回显这个,但是回显的东西使我的输入框和文本框失去了它们的样式和设计。

<script>
function deleteItem()
{
   var resp = confirm("Do you want to delete this item???");
   if (resp == true) {
      //do something
   } 
   else {
      //do something
   }
}
</script>

使用onClick调用此函数

您可以更好地使用以下方法

 <a href="url_to_delete" onclick="return confirm('Are you sure you want to delete this item?');">Delete</a>

我想提供我的方法:

<form action="/route" method="POST">
<input type="hidden" name="_method" value="DELETE"> 
<input type="hidden" name="_token" value="the_token">
<button type="submit" class="btn btn-link" onclick="if (!confirm('Are you sure?')) { return false }"><span>Delete</span></button>
</form>
function ConfirmDelete()
{
  return confirm("Are you sure you want to delete?");
}


<input type="button" onclick="ConfirmDelete()">

对于选择选项框,要做到这一点要困难得多。 下面是解决方案:

<select onchange="if (this.value == 'delete' && !confirm('THIS ACTION WILL DELETE IT!\n\nAre you sure?')){this.value=''}">
    <option value=''> &nbsp; </option>
    <option value="delete">Delete Everything</option>
</select>

对于“删除确认消息”使用:

                       $.ajax({
                        type: "POST",
                        contentType: "application/json; charset=utf-8",
                        url: "Searching.aspx/Delete_Student_Data",
                        data: "{'StudentID': '" + studentID + "'}",
                        dataType: "json",
                        success: function (data) {
                            alert("Delete StudentID Successfully");
                            return true;
                        }
